Superfund record of decision (EPA Region 10): US DOE Idaho National Engineering Laboratory, Operable Unit 18, Idaho Falls, ID, September 1993
The ROD addresses the contamination of Pit 9 at the Radioactive Waste Management Complex (RWMC), Subsurface Disposal Area (SDA), at the Idaho National Engineering Laboratory (INEL). The selected remedy for Pit 9 will use a combination of chemical extraction, physical separation, and/or stabilization technologies to recover contaminants and reduce the source of contamination. The major components of the remedy are: Proof-of-Process (POP) to demonstrate that designated performance objectives and cleanup criteria are attainable; Limited Production Test (LPT) to give a high degree of confidence that performance objectives and cleanup criteria can be met and all systems are reliable before full-scale remediation; Excavation and segregation of waste with greater than 10 nanocuries per gram transuranic (TRU) elements for input into the treatment process; Treatment of waste using chemical extraction, physical separation, and/or stabilization to remove radionuclides and hazardous constituents and to reduce the toxicity, mobility, and/or volume of those wastes that remain; Treatment of listed hazardous waste to levels which will allow for delisting of the waste (for material being returned to the pit) in accordance with the Resource Conservation and Recovery Act (RCRA) and the Idaho Hazardous Waste Management Act (HWMA); Return of treated materials to Pit 9 (treated materials will contain less or equal to 10 nanocuries per gram TRU elements and meet regulatory standards for hazardous substances of concern); Volume reduction by approximately 90% (for material undergoing treatment); and Onsite storage of concentrated waste residuals in accordance with ARAs until final disposal.
